The
following list summarizes selected foods containing high
levels of potassium, as measured by the United States
Department of Agriculture.

Those who
need to increase their potassium intake can select foods
from this high potassium food summary list. It is not
necessary to take potassium supplements, to achieve a high
level of potassium nutrition.

Notes:
I changed some numbers to more closely reflect a more
appropriate "Common Measure".
This is a list of "basic foods".
Many fast foods contain high amounts of potassium, but I
omitted them due to all the other garbage they contain. The
same is true for soups and cereals.
